Refer to Fig. 1, the utility model is applied to circuit breaker 1, and described circuit breaker 1 can be breaker of plastic casing 1, utilizes the shell of plastic material to carry out electrical isolation, as shown in Figure 1, exemplified with a kind of structural representation of circuit breaker 1 vertical profile, wherein, circuit breaker 1 comprises: Shell of circuit breaker 11, the lid 12 that Shell of circuit breaker 11 front is arranged, fixed contact 13 in housing, moving contact 14, arc control device 15, operating mechanism 16, electromagnetic system 17 and terminal block 18 etc., wherein, fixed contact 13 and terminal block 18 lay respectively at the relative both sides of circuit breaker 1, wherein, Shell of circuit breaker 11 entirety is square body, described relative both sides are the both sides of minor face on described Shell of circuit breaker 11, be convenient to wiring, in one embodiment, mainly for be fixed contact 13 and terminal block 18 wiring protection, described fixed contact 13 and terminal block 18 are wired to power end and load end respectively, certain circuit breaker 1 internal structure is varied, not be exemplified as limit with above-mentioned, if but have exposed electric component wiring, all can use breaker connection shield plate 2 of the present utility model.
As shown in figs. 2 a and 2b, described lid 12 is provided with the opening exposing described operating mechanism 16, and, also can be provided with such as " ON " of instruction circuit breaker 1 operating state, printed words such as " OFF ", described lid 12 is being provided with multiple groove 121 exposing the metallic screw of link to being less than side, due to as previously mentioned, in the present embodiment, circuit breaker 1 wiring has fixed contact 13 and terminal block 18 two parts, and point to be positioned at circuit breaker 1 both sides relatively, therefore, metallic screw and groove 121 also need two groups, so in other embodiments, if only there are place's parts to need wiring also can only establish one group, not be limited with the present embodiment, in one embodiment, each groove 121 of described lid 12 at least side can in lid 12 edge by linear array, described lid 12 also can be respectively equipped with multiple described groove 121 in relative both sides, fixed contact 13 below the groove 121 being respectively used to corresponding described relative both sides and terminal block 18, the metallic screw in the groove 121 of described relative both sides is used for fixing described fixed contact 13 and terminal block 18 and outside wiring.Certainly in other embodiments, described each groove 121 also can be not according to linear array.In one embodiment, described groove 121 in described lid 12 side along open and to lower recess (by seamed edge 1211 described in downward projection) formed groove 121, from diagram, can such as cross section be the U-lag of U-shaped;
As shown in Figure 2 b, described lid 12 is provided with the seamed edge 1211 of protrusion in the back side at each described groove 121 edge, is actually in the example shown and protrudes outward towards paper.
Again as shown in Figure 2 a, described lid 12 is also formed with multiple shrinkage pool 122; Described shrinkage pool 122 is used as installing hole, inside establish the installation screw of fixing such as wiring or circuit breaker 1 internal part, described shrinkage pool 122 can be annular, in one embodiment, by two parallel lines and connect the annular that described two parallel lines form with two camber lines of side respectively, be similar to " track type ".
As shown in figs. 3 a and 3b, a kind of breaker connection shield plate 2 provided by the utility model, for being incorporated into described lid 12 to cover each described wiring, it comprises: plate body, the boss 21 being located at plate body and grab 22 etc.Concrete structure is as follows:
Described plate body, preferably, the matching form of its shape and described circuit breaker 1 lid 12 closes, and becomes the entirety that edge is neat after making to cover, if therefore described lid 12 is square, then described plate body also can be corresponding square configuration.
From Fig. 3 a, multiple described boss 21 is the bottom surfaces can being located at described plate body, combine with described each shrinkage pool 122 respectively for form fit, thus restriction lid 12 planar does translational motion at it, as previously mentioned, described shrinkage pool 122 can be such as " track type ", and therefore described boss 21 also can be corresponding " track type ".
See also Fig. 3 b, multiple described grab 22 can extend formation from described plate body bottom surface, in described multiple grab 22 one or more respectively correspondence stretch into each described groove 121 and be snapped in described seamed edge 1211, with fixing described plate body in lid 12.
Specifically, described Shell of circuit breaker 11, in each groove 121 of described lid 12 side, is positioned at middle each groove 121 and stretches at least two grabs 22 to be snapped in respective seamed edge 1211; The each groove 121 being positioned at outside stretches into a grab 22 respectively to be snapped in respective seamed edge 1211, thus restriction lid 12 is away from the motion on Shell of circuit breaker 11 direction.Due in the above-described embodiments, groove 121 is by linear array, then grab 22 is also that linear array is located at described plate body, and be to arrange in the opposite direction in the hook part stretching into the grab 22 in outermost two grooves 121, and then the tension force formed in a straight line, make whole breaker connection shield plate 2 fixing more firm.
So, it should be noted that, in other embodiments, if groove 121 is not linear array, and has and be greater than two, then grab 22 only needs contraposition to arrange, and be arranged in outermost groove 121 in all directions and all only can stretch into a grab 22, and hook is in the rib of stretched into groove 121, preferably hook is more outermost in rib, therefore not by above-described embodiment is limited.
As shown in Figures 4 and 5, circuit breaker 1 frontal state during breaker connection shield plate 2 is not installed in Fig. 4 display, and visible metallic screw is exposed in circuit breaker 1 front; When installing breaker connection shield plate 2 namely as shown in Figure 5, covering completely from circuit breaker 1 front thus having isolated the electrification device such as metallic screw and wiring.
In sum, the utility model provides a kind of breaker connection shield plate and circuit breaker, the housing front of described circuit breaker is provided with lid, described lid is provided with multiple groove exposing the metallic screw of link to being less than side, described lid is provided with seamed edge in the back side at each described groove edge, and described lid is also formed with multiple shrinkage pool; Described breaker connection shield plate is used for being incorporated into described lid to cover each described wiring, and wherein, described circuit breaker shield plate comprises: plate body; Multiple boss, is located at described plate body, combines with described each shrinkage pool respectively to form fit; From multiple grabs that described plate body extends, in described multiple grab one or more respectively correspondence stretch into each described groove and be snapped in described seamed edge, with fixing described plate body in lid; Utilizing cap structure to carry out being designed to can the shield plate well fixed of buckle and male-female engagement, covers to isolate live part to eliminate safe hidden trouble from front.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
